The term arthritis literally means inflammation of a joint but is generally used to describe any condition in which there is damage to the cartilage. Damage of the cartilage in the shoulder joint causes shoulder arthritis.
A break in a bone that makes up the shoulder joint is called a shoulder fracture. Clavicle and humerus fractures can occur by a direct hit from a motor vehicle accident, collision or fall. A fracture of the scapula can occur by high-energy trauma during an accident from a high-speed motor vehicle.
Pain in the shoulder suggests a shoulder injury which is more common in athletes participating in sports such as swimming, tennis, pitching and weightlifting. The injuries are caused due to the over usage or repetitive motion of the arms.
The rotator cuff is a group of tendons in the shoulder joint providing support and enabling a wide range of motion. Major injury to these tendons may result in tear of these tendons, a condition called rotator cuff tear.
The term SLAP (superior –labrum anterior-posterior) lesion or SLAP tear refers to an injury of the superior labrum of the shoulder. The labrum is a ring of fibrous cartilage surrounding the glenoid for stabilization of the shoulder joint.
Shoulder instability is a chronic condition that causes frequent dislocations of the shoulder joint.
